This extension is used to define correlations between types of users and permissions. If you send request packet containing the get-permission-descriptor operation, the respond from the server will contain permission level in the level node nested into the extension node. The graphical representation of the construction is as follows:

This node can be empty, or contain one of the following values:

• client. The parameter is visible to customers.
• domain. The parameter is visible to webspace users.
• mail. The parameter is visible to mail account users.
